CME caused by ticking Assemblicator

(Re)loading a previously loaded and working world after adding and configuring some automated Formulaic Assemblicators (one for 4 stone→stone bricks, one for 4 sand→sandstone) crashes the server each time.

I successfully hacked a hotfix to save this world by constructing a CopyOnWriteArrayList from the getRecipeList() result before looping over it at mekanism.common.util.MekanismUtils.findMatchingRecipe(MekanismUtils.java:1470).

Stacktrace:
